A combined fuel economy of 27 MPG isn’t exactly highly efficient, but for the 2017 Infiniti QX30 2.0L and its target buyer, it’s acceptable. This isn’t a Prius competitor; it’s a stylish hatchback with a slightly higher driving position, aimed at urban professionals who want design and a touch of luxury over maximum fuel economy. They are willing to trade some MPGs for the QX30’s unique styling and the confident performance of its turbocharged engine.

City and highway fuel performance

The QX30’s EPA estimates are 24 MPG in the city and 33 MPG on the highway. The city figure shows the effect of stop-and-go traffic, where the turbocharged 2.0L engine can use more fuel as it builds boost. The seven-speed automatic transmission, while generally smooth, can sometimes hesitate in city environments, causing more aggressive use of the accelerator and reduced fuel economy. On the open road, the QX30 cruises comfortably, allowing the engine to operate efficiently. The 33 MPG highway rating is achievable, especially with careful driving and cruise control.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2017 Infiniti QX30 2.0L is $1,944. This is based on driving 15,000 miles per year and assuming a national average fuel price. Your fuel costs will vary depending on your driving, the type of fuel you use (premium is recommended), and local fuel prices. However, the $1,944 provides a benchmark for comparing the QX30’s costs to other vehicles. Drivers in states with higher gas prices will pay more, while drivers logging fewer miles will see lower annual expenses.

Real-world expectations

While the EPA estimates provide a standard comparison, real-world fuel economy often differs. QX30 owners report MPG figures near the EPA numbers, but rarely much higher. Expect to see closer to 22-25 MPG in mixed city/highway driving and possibly over 30 MPG on longer highway trips with consistent speeds. Aggressive driving, frequent short trips, and cold weather can hurt fuel economy. Gentle acceleration, smooth braking, and well-maintained tires can help you get closer to the EPA’s projections. You can find QX30 MPG across all years to see how they compare.

How it compares

The QX30’s fuel economy is competitive, but not best-in-class. The Mercedes-Benz GLA250, sharing the same engine and transmission, achieves a slightly better 28 MPG combined. The BMW X1, another popular choice, gets a combined MPG of 25, focusing on driving feel over economy. The Lexus UX, with its hybrid powertrain, achieves a much higher 42 MPG combined. The Audi Q3 offers 25 MPG, similar to the Infiniti. Many QX30 buyers also consider these vehicles and are prepared to accept the fuel economy in return for the QX30’s styling and interior.

Tips to maximize efficiency

One simple tip is to ensure proper tire inflation. Underinflated tires increase rolling resistance, making the engine work harder and use more fuel. Check your tire pressure regularly, before each long trip, and inflate them to the recommended pressure on the sticker inside the driver’s side doorjamb.

Avoid aggressive acceleration and braking. The QX30’s turbocharged engine responds well to smooth throttle inputs. Rapid acceleration burns more fuel than gradually building speed. Anticipate traffic and avoid sudden braking; coasting to a stop is more efficient than hard braking.

Minimize idling. Letting the engine idle consumes fuel without covering distance. If you’re stopped for more than a minute or two, shut off the engine. Modern engines restart quickly, and the fuel saved adds up.

Use cruise control on the highway. Cruise control maintains a steady speed, preventing speed changes that can decrease fuel economy. Use cruise control on open roads to improve efficiency and reduce driver fatigue. Cruise control may not be the best choice in hilly terrain; it’s often more economical to let your speed drop slightly on inclines rather than forcing the engine to maintain a constant speed.
